Therefore, this invention proposes a wire drawing machine for stainless steel bars.

[0007] The effect achieved by the above components is to use a conveyor belt to transport stainless steel bars for wire drawing.

[0008] Preferably, two columns are fixedly connected to the upper surface of the chassis, a push plate is slidably connected inside the columns, a cylinder is fixedly connected to the lower surface of the push plate, the lower surface of the cylinder is fixedly connected to the chassis, and a feeding box is fixedly connected to one side of the columns.

[0009] The effect achieved by the above components is to push stainless steel bars onto the conveyor belt.

[0010] Preferably, a guide rod is slidably connected inside the push plate, and the guide rod is distributed on both sides of the push plate.

[0011] The effect achieved by the above components is to guide the reciprocating motion of the push plate by the cylinder.

[0012] Preferably, the machine casing is equipped with a waste cleaning device. The waste cleaning device includes a slot, which is located inside the machine casing directly below the wire drawing wheel and the drawing wheel. A fixing plate is fixedly connected to one end of the slot, and a handle is slidably connected inside the fixing plate. A scraper is fixedly connected to the end of the handle away from the fixing plate.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, when an automatic feeding device is needed for drawing stainless steel bars, the second motor is turned on. The rotation of the second motor drives the pulley connected to the second motor to rotate. The rotation of the pulley connected to the second motor drives the belt drive, which in turn drives another pulley to rotate. The rotation of the other pulley drives the roller fixedly connected inside the pulley to rotate. The rotation of the roller drives the conveyor belt. Then, the stainless steel bar to be drawn is placed on the feeding box. The inclined angle of the feeding box causes the stainless steel bar to be drawn to roll towards the end closer to the second motor. The cylinder is turned on, and the cylinder pushes the push plate to move up and down reciprocally. The up and down reciprocating motion of the push plate will send the stainless steel bar to be drawn that has rolled into the push plate into the conveyor belt. The conveyor belt conveys the stainless steel bar to be drawn to the drawing equipment at the other end.

[0022] In this invention, when the waste cleaning device is needed after the wire drawing is completed, a waste collection bag is placed below the discharge port. The handle is pulled away from the end of the spring. The handle moves away from the spring, causing the scraper to move along the slide bar towards the discharge port. At this time, the spring is in a stretched state. The scraper moves towards the discharge port, causing the waste inside the groove to move out towards the discharge port and fall into the collection bag below the discharge port. After the waste is cleaned, the handle is released, and the spring contracts, causing the scraper to move backward and return to the initial state. Attached Figure Description

The effect achieved by the above components is: to use the conveyor belt 607 to transport stainless steel bars for wire drawing. Two columns 608 are fixedly connected to the upper surface of the casing 1. A push plate 609 is slidably connected inside the columns 608. A cylinder 612 is fixedly connected to the lower surface of the push plate 609, and the lower surface of the cylinder 612 is fixedly connected to the casing 1. A feeding box 611 is fixedly connected to one side of the columns 608. The effect of the above components is to push stainless steel bars onto the conveyor belt 607. A guide rod 610 is slidably connected inside the push plate 609, and the guide rod 610 is distributed on both sides of the push plate 609. The effect of the above components is to guide the reciprocating motion of the push plate 609 by the cylinder 612.

[0032] Reference Figure 4 and Figure 5 As shown in this embodiment: the waste cleaning device 7 includes a slot 71, which is located inside the housing 1 directly below the wire drawing wheel 2 and the pulling wheel 4. A fixing plate 75 is fixedly connected to one end of the slot 71. A handle 73 is slidably connected inside the fixing plate 75. A scraper 72 is fixedly connected to the end of the handle 73 away from the fixing plate 75. The effect of these components is to facilitate the cleaning of waste debris that falls into the slot 71 during wire drawing. Two sliding rods 77 are slidably connected to both sides of the scraper 72. The two ends of the sliding rods 77 are fixedly connected to the slot 71 and the fixing plate 75, respectively. The effect of these components is to guide the scraper 72 when it is pulled within the slot 71, reducing the shaking when the scraper 72 is pulled. A spring 74 is fitted onto the arc surface of the sliding rod 77. The two ends of the spring 74 are fixedly connected to the inside of the slot 71 and the fixing plate 75, respectively.

[0033] Working principle: When the automatic feeding device 6 is needed for drawing stainless steel bars, the second motor 602 is turned on. The rotation of the second motor 602 drives the pulley 604 connected to the second motor 602 to rotate. The rotation of the pulley 604 drives the belt 605 to drive another pulley 604 to rotate. The rotation of the other pulley 604 drives the roller 603 fixedly connected inside the pulley 604 to rotate. The rotation drives the conveyor belt 607 to drive the transmission, and then the stainless steel bar to be drawn is placed on the feeding box 611. The feeding box 611 has an inclined angle, which will cause the stainless steel bar to be drawn to roll towards the end closer to the second motor 602. The cylinder 612 is opened, and the cylinder 612 pushes the push plate 609 to move up and down. The up and down movement of the push plate 609 will send the stainless steel bar to be drawn that has rolled into the push plate 609 into the conveyor belt 607. The conveyor belt 607 conveys the stainless steel bar to be drawn to the drawing equipment at the other end.

The handle 73 moves away from the end of the spring 74, causing the scraper 72 to move along the slide rod 77 towards the end of the discharge port 76. At this time, the spring 74 is in a stretched state, and the scraper 72 moves towards the end of the discharge port 76, causing the waste inside the groove 71 to move out towards the end of the discharge port 76 and fall into the collection bag below the discharge port 76. After the waste cleaning is completed, the handle 73 is released, the spring 74 contracts, and the scraper 72 moves backward, causing the scraper 72 to return to its initial state.
